WRENCH.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed October 21, 1907. Serial No. 398,421.

To all whom it may concern:

Be it known that I, NAPOLEON DUSSAULT, a citizen of the United States,and a resident of the town of New Brunswick, in the State of New Jersey,United States of America, have invented certain new and usefulImrovenients in Wrenches, of which the folfbwing is a full, clear, andexact description.

This invention relates to wrenches and the object is to provide a quickacting device that can be set to any position instantly and locked orunlocked with great ease and rapidity.

The invention consists essentially of a shank provided with a fixed headand a movable jaw similar to those employed in ordinary wrenches. Themovable jaw is provided with a pivoted block, said block having itsinner face toothed to cooperate with the toothed edge of one face of theshank. A resilient member holds said block normally out of engagementwith the teeth of the shank,'while a pivoted linger member having aneccentric portion in contact with the pivoted block, is adapted to forcesaid block against the toothed face of the shank when so desired.

In the drawings which illustrate my invention:Figure 1 is a plan view ofthe wrench turned on its side. view partly in section. of the wrench.

Referring to the parts, 1 designates a shank of cast steel orothersuitable material, provided with a fixed head 2, and a movable jaw3.

4 designates a band adapted to hold the jaw 3 in slidable relation tothe shank and alsoto contain at its front side the locltfiig lever. Theband t is provided with aredss 5 adapted to contain the block 6 havingin its inner face a plurality of teeth adapted to engage and cooperatewith similar teeth formed in the shank 1. The block (3 is pivoted nearits upper end at 6, and at its lower end is provided with a curvedportion 8 adapted to cooperate with the eccentric end 9 of the finerlever 10, said lever being held in position y means of the pin 11.

Fig. 3 is a front "iew ignated by 10 in order to facilitate its out:ward movement .when resting a ainst the handle 13 of the wrench. The shank 1 is provided with a plurality of teeth 12 forming Fig. 2 is asimilar plan I The finger lever 1() is given a slight twist at its lowerend, as dosa rack which is adapted to cooperate with the teeth of theblock 6. The lower end of the pivoted block 6 is held normally out ofengagement with the teeth 12 of the shank by means of a resilient member14. As shown in Fig. 2, this resilient member consists of of a block ofrubber or like material inserted within the recess between the upper endof the member 6 and the metal of the sliding jaw 3.

In the operation of the device, the finger lever 10 is thrown outwardlyto the position shown in dotted lines in Fig. 1, during which movementthe eccentric end 9 of the lever releases the block 6. The jaw 3 is thenmoved to the desired position. The resilient member 14 normally throwsthe upper end of the pivoted member 6 inwardly toward the shank of thewrench, while the lower end of said member is maintained out ofengagement wit-h the teeth of-the shank. \Vhen the aw 3 is set to thedesired position, the finger lever is pressed downwardly parallel withthe shank, as shown in Figs. 1 and 2. the eccentric end 9 of said leverforcing the block 6 into engagement with the teeth 12.

' The jaws are thus firmly locked in position.

The member 1 c may be of any resilient material and may be placed in anyconvenient position with respect to the block 6, in order to serve thedesired purpose.

Having thus described my invention, what I claim is In a wrench, a shankhaving a fixed jaw at one extremity thereof, a slidable jaw mounted onsaid shank, a plurality of teeth on the face of the shank adjacent thejaws, a lever pivoted within said slidable jaw, a toothed block integralwith one extremity of said lever and adapted to engage the teeth of theshank, a resilient member mounted be.- t-ween the jaw and the oppositeend of the lever and adapted to maintain said block normally out ofengagement with the shank, a lever pivoted to said movable jaw adjacentthe block, and an eccentric extremity on said lever adapted to forcesaid block into engagement with the shank.

In witness whereof .l have hereunto set my hand in the presence of twowitnesses.
